Our new place came with a satellite for TV (there's no cable up here), but we don't watch enough TV to pay more than $100/month for it. So, the unsightly cords hanging out of the wall are even more so because they serve no purpose. And the likelihood that we're EVER going to have a TV in the music/guest room is so low, we just pushed it into the wall and set about covering it up.

Luckily, I had a blank plate in my stash of electrical box plates (yes, I have a stash of electrical box plates, c'mon!). Annnnnnnd I went ahead and painted it up to look like a door and glued a bead to it for a doorknob. My own little fairy door!
